SHIPPING-CONTAINER BINDER.

Application filed January This invention aims to provide a binder which will rotect the corners and angles of a shipping container completely, the binder being adjustable to fit containers of diiierent sizes, and being so constructed that it will retain its place on a shippingcontainer without resorting to the use of diagonal ties, or tacks, nails, oranything else of a like sort which engages the container, the article being clearly distinguished, in this respect, from common angle iron, reinforcements which are fastened to the box by se curing elements which enter the'bok.

It is within the province of the disclosure to improve generally and to enhance the utility of devices 0t that type to which the invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the mvention herein disclosed, may be made within the scope of what is claimed, without departin from the spirit of the mvention,

tainer 14 of any desired sort, for instance, the box shown in my co-pending'app'lication Serial Number 82,314 filed on the-19th day of January, 1926; although the, hindermay be used, of course, upon any kind of a box or container, whether of wood, metal, or woven material.

The binder embodies a set of corner brackets 1 and a set of corner brackets 2, each bracket 1 comprising transverse arms 3 and 4, and each bracket 2 comprising transverse arms 5 and 6, each of the brackets 1 including a longitudinal arm 7, and each of the brackets 2 comprising a longitudinal arm 8. The arms 3, 4, 5, 6, 7 and 8 are in the form of angle members, each including rectangularly disposed flanges 9, 7

Each arm 3 or 7 or 4 of the bracket 1 is disposed at right angles to the other arms of that bracket, and each of the arms 8, 5 or 6 of the bracket 2 is disposed at right angles to the other arms of that bracket. The flanges of the arms of every angle brackat are supplied at their outer ed es with trough-shaped longitudinally eXten ed overhanging wmgs 10. Extension and connection pieces 11 are provided. The parts 11 are called connection elements, because they join and connect the corner brackets with each' other. The parts 11 join the corresponding transverse arms 6-6 and 5 5 of the corner brackets 2, and join the corresponding arms 4-4 and 3-3 of the corner brackets 1, extension pieces also joining the longitudinal arms 7 of the brackets 1 with the longitudinal arms 8 of the corner brackets 2, the arms 9 being considerably longer than the arms 8, if desired, as clearly shown in Figure 1 of the drawings.

Each extension or connecting piece 11 tudinal lines 27 'to' form the wings 10. The

holding the binder in place on a container? meaning thereby that when the binder IS in place on the container 14, as shown in Figure 1, it will stay there, by its inherent construction, and it being unnecessary'to fasten any part of the binder to the container by nails, screws or any other kind of securing elements, it being equally unnecessary to connect spaced parts of the binder, diagonally, transversely, or in any other way, by ties, such as wires, straps and the like. In other words, the wings 10 hold the arms and the extension pieces together against separation transversely, and the aforesaid step by step mechanism holds the extension pieces and the arms against separation lengthwise. The step by step mechanism, upon which considerable emphasis has been laid hereinbefore, may embody racks 15 on .with stops 30 adapted to the flanges 12 of the extension pieces 11, and resilient inwardly inclined pawls 16, struck from the flan es 9 of the arms and adapted to engage re easabl with the racks 15, in a way which will be understood readily by those skilled in the art. The racks 15 at the respective ends of the member ll'face in opposite directions, and in order to prevent the member 11 from sliding toofar in one direction, whilst the artido is being assembled, and permitting one set of the pawls 16 to come into contact with racks upon which they can not hold, the member 11 is supplied intermediate its ends cooperate with the ends of the arms.

The particular way in which the various arms are connected and constructed may be varied, but, if desired, recourse may be had to the blank 17 shown in Figure 3, the

blank being provided in one edge with a V-shaped notch 18, and being supplied in its 0 posite edge with a shallow rectangular note 19. The blank is turned over on longitudinal lines 20 to form the wings 10, the blank being folded transversely, as at 21, at the apex of the notch 18, to bring the edges of the notch 18 together as shown at 22, the notch 19 becoming, as shown in Figure 5, an opening 23 located at the inner en s of two of the arms and interrupting the overhanging wings 10. Referring to Figure.

2 there is shown a blank 24 having an outstanding tongue 25 at one'end. The blank 2a is folded along a longitudinal line 26 to form the flanges, and isturned along longitongue 25 is disposedat right angles to the flanges and closes the end of the angle memher as shown at 28 in Figure 4. The end of the member shown in Figure 4 is inserted into the angle of the member shown in Fig ure 5, and the parts may be held together by spot welding or otherwise, to constitute the corner bracket shown in Figure 6, or

the corner bracket shown in Figure 7.

The device claimed, shown and described,

is simple in construction, easily assembled, and inexpensive. It may be used on any style box made of any material, whether; wood, metal, fibre, paper or cloth, netting or mesh work. By the use of the device described, a box may be constructed of straight panel pieces without fastening devices of any kind, and may be held together and protected adequately. The article is almost indestructible and adds greatly to the carrying strength of any box on which it is used. Space is economized, because boxes reinforced by the device forming the subject matter of this application, may be stacked to great height, without crushing. The article is collapsible and may be bundled and shipped in small compass, and it has a returnable or resale value. The fact that the article has a returnable or resale value cannot be too strongly emphasized, as it saves cost of material, time and labor. This is important both to the consumer and to the manufacturer.
